Carrot Oil

Staniszewska and Kula (2001) analyzed the composition of a lab-prepared oil of Daucus carota L. ssp. carota that was obtained from wild carrot fl owering umbels growing in their naturalized habitat in Poland. Using a combination of GC and GC/MS, the oil was found to contain the following constituents:

alpha-thujene (0.32 percent)
